Currently have nice long docker compose file that hosts my PiHole V6 container (along with a bunch of other containers) however, reason i ask this question is because whenever I go to pull an updated image and recreate the container I experience about 20 minutes of no DNS resolution which to my knowledge is due to the NTP clock being out of sync.

What’s the best way to host a DNS sinkhole/resolver that can mitigate this issue?

Was thinking of utilizing Proxmox & LXC but I suspect I’ll get the same experience.

Update: Turns out PiHole doesn’t support two instances, I got both of them on separate devices also set the 2nd DNS server in my routers WAN & LAN DNS settings which did in fact split DNS between both instances however, I lost access to my routers web-ui, my Traefik instance & reverse proxies died and I lost all internet access.

So, don’t do what I did.

    I think something else may be wrong if it breaks for 20 minutes.

    When I originally setup my PiHole many, many, many months ago when I was still learning the Docker engine I had little to no issue.

    I don’t know what caused it either being a power-outage or network loss but ever since I’ve been experiencing DNS related issues (I suspect it’s NTP not syncing), some days I’ll wake up before work realizing “oh shit I have no internet access” frantically trying to fix the issue.

    I think i might take the advice of other commenters here and host two PiHole servers on separate devices/stacks, just got to hope my router supports it.
